IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 132,025, dated October8, 1872.

To all whom it may concern:

Be it known that I, J osEPH FnANgoIs MA- RIE RIGOD, of Paris, in theRepublic of France, have invented a new and ImprovedApparatusfor'Oarbureting Air; and I do hereby declare the following,when taken in connection with the accompanying drawing and the lettersof reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawing constitutes part of thisspecification, and represents, in

Figure 1, a longitudinal section, and in Fig. 2 a transverse section.

The object of my invention is to provide an apparatus suitable forcarburetin g air by means of mineral or vegetable essences orhydrocarbons and applying the carbureted air for lighting and heatingpurposes. This apparatus consists of an external metal cylindercontaining another metal cylinder having lateral helical openings ateach of its faces, and this cylinder, which is divided into fourcompartments, is fixed to a horizontal shaft which turns with thecylinder in two bearings by the simple reaction of the air. The internalcylinder has on its sides a convex cap or cover, in the interior ofwhich there is a tube which supplies the air to be'carbureted. Thistube, which I call a dividing tube, consists of an external tube havingin its interior at the center a small capillary tube, the lower end ofwhich is immersed in the carbureting-liquid, which is poured into theexternal cylinder. The air is forced by a blower through thedividing-tube and through the lateral and helical openings, where itbecomes saturated with the carburetin g liquid, and. it then escapesthrough an opposite opening in asufficiently-carbureted state to burnwith a beautiful-flame.

B represents an external cylinder surrounding an internal cylinder, 0,having lateral helical openings in its two sides, and it is divided intofour compartments, D D D D, and fixed to a shaft, J, which turns in twobearings, K K, by the reaction of the current of air. The cylinder 0, asseen in Figs. 1 and 2, is not so large as the cylinder B, and has at theside E a convex cap or cover, P, in which there is the outlet of thedividing-tube which supplies the air, and this dividing-tube consists ofa small capillary tube, F, extending to near the bottom of theapparatus, and also another tube, G, and the level of the liquid isshown at N N, and M are the legs which support the'apparatus. The liquidis introduced by the opening or pipe H and allowed to rise to the levelN N, the air being supplied at a low pressure by means of a specialbellows or fan to the pipe Gr, so that when it escapes through theorifice 0 there will be sufficieht suction to enable the liquid to risein the capillary tube F; The liquid, when it arrives in contact with'theair, becomes absolutely divided and strikes threads of metal or thosemade of vegetah e...9. illlil i matter macedinsufficient quantity ineach oflthe. compart nents D DD D, the elfect of which istli'at the airwhich'passes out through the pipe or opening H is perfectly saturatedwith the carburetingessence and burns with an intense flame. Thepressure of the air also causes the cylinder 0 to rotate, the effect ofwhich is to divide the essence or liquid and cause it to come in contactwith fresh air and the air in contact with fresh liquid, and thuscooling is impossible, and at the same time the liquid is not heated andcondensations are avoided. This apparatus may also be employed withoutthe threads of-metal or of vegetable or animal matters, and usinginstead of them cloth made of the threads, and in this case thecapillary tube may be dispensed with. In another arrangement, instead ofplunging the capillary tube or tubes in the liquid with'which thethreads or cloth are in contact, the tube or tubes may be placed in avessel containing a heavy oil, in order to give more density to theflame, and in all cases where a pair of bellows are used they areprovided with India-rubber springs, in order to supply the air withregularity and without shocks. The cylinder 0 may be modified in variousways without affecting the working of the apparatus; thus, the two sidesmaybe formed of plates with open spaces,

or with spaces covered with metallic cloth, and

in these two cases the convex cap or cover P is indispensable. Thecylinder 0 can also be -incl'osed in lateral cases full or half full ofliquid, the periphery of the cylinder being formed 1 of sheet metalhaving in it a number of holes or made entirely of metallic cloth. Thecapillary tubes can also be replaced by a simple siphon elevated betweenthe cap P and the perdivided at its end and in connection with acapillary tube, the latter having its lower end immersed in the liquid,substantially in the manner and for the purpose described.

In testimony whereof I have signed my name to this specification beforetwo subscribing witnesses.
